NOTICE OF VIOLATION I

1 Union Electric Company Docket No.: 50-483

! Callaway Plant License No.: NPF-30 1

! . During an NRC inspection conducted on October 21 through December 9,1996, one l l violation of NRC requirements was identified, in accordance with the " General Statement

, of Policy and Procedure for NRC Enforcement Actions," NUREG-1600, the violation is

} listed below:

Criterion IX of Appendix B to 10 CFR Part 50 states, in part, " Measures shall be ,

established to assure that special processes, including . . . nondestructive testing,  !

are controlled and accomplished . . . using qualified procedures in accordance with  !

applicable, codes, standards, specifications, criteria, and other special '

requirements."

Section 2.3 of Procedure ETP-BB-01309," Steam Generator Eddy Current Testing Acquisition and Analysis Guidelines," Revision 7, states, "All techniques used shall be qualified in accordance with Appendix H of the EPRI PWR Steam Generator  ?

Examination Guidelines., Revision 4."

Westinghouse Report DDM-96-009," Documentation of Appendix H Compliance and

- Equivalency," identifies the qualified Appendix H analysis span and phase rotation settings for plus point coil examination of tube expansion transition regions to be, respectively, one half screen height response to a 40 percent notch and rotation set to 20 degrees for a 100 percent through-wall notch.

Contrary to the above, analysis of plus point probe eddy current data during Refueling Outage RF8 was not controlled to assure use of Appendix H qualified settings for span and phase rotation, as evidenced by:

1. Specific direction was not provided by the primary eddy current analysis contractor, Westinghouse, to the analysts on span and phase rotation I settings to be used for analysis of plus point coil examination data. I

2. Procedure ETP-BB-01309, Revision 7, provided span and phase rotation settings for only the rotating pancake coil. These settings differed from those used in the qualification of the plus point coil and were inappropriate for use with that coil.

This is a Severity Level IV violation (Supplement I) (50-483/9610-01). i i

Pursuant to the provisions of 10 CFR 2.201, Union Electric Company is hereby required to submit a written statement or explanation to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, D.C. 20555 with a copy to the Regional Administrator, Region IV,611 Ryan Plaza Drive, Suite 400, Arlington, Texas 76011, and a copy to the NRC Resident inspector at the facility that is the subject of this Notice, within ]
